Question

3 Two masses on a slope Two masses are on a slope of angle $\theta$ and are connected by a rope. $m_1$ $m_2$ $\theta$ Mass 2 is on frictionless wheels. The friction between the mass 1 and the slope has static and kinetic coefficients $\mu_s$ and $\mu_k$. 1. If the boxes are stationary (not sliding), draw two free body diagrams: one for each mass. 2. Once again, if the boxes are stationary, what is the frictional force between $m_1$ and the surface? 3. Now, if the boxes are sliding down the surface, what is their acceleration? 4. Test some limits of your answer to part 3. For each, include a physical explanation of why that makes sense (or why it doesn't apply). (a) What happens when $\mu_k \to 0$. (b) What happens when $\theta \to 0^\circ$. (c) What happens when $\theta \to 90^\circ$.

3 Two masses on a slope Two masses are on a slope of angle heta and are connected by a rope. Mass 2 is on frictionless wheels. The friction between the mass 1 and the slope has static and kinetic coefficients mu _(s) and mu _(k). If the boxes are stationary (not sliding), draw two free body diagrams: one for each mass. Once again, if the boxes are stationary, what is the frictional force between m_(1) and the surface? Now, if the boxes are sliding down the surface, what is their acceleration? Test some limits of your answer to part 3. For each, include a physical explanation of why that makes sense (or why it doesn't apply). (a) What happens when mu _(k)->0. (b) What happens when heta ->0deg . (c) What happens when heta ->90deg . 3 Two masses on a slope Two masses are on a slope of angle and are connected by a rope m2 Mass 2 is on frictionless wheels.
